ketumAla

Ketu-Mala
Ketumala to the west of Meru, through which river Chakshu (Oxus) flows, corresponds to western Turkestan. It is believed to cover ‘practically the whole of the ancient Bactria which included the whole of the present Afghan Turkistan (north of Hindukush), the lower Harirud valley, the basin of Murkhab Kashka system (all south of the old bed of Amu Darya) and the basins of the Surkhan, Kafirnigan, Vakhsh and Yaksu rivers…’
